  Official Ruling
  When Donatello enters the battlefield, his triggered ability will check to see if you control an artifact. If you don't, the ability won't trigger at all. If the ability does trigger, it will check again as it tries to resolve. If you no longer control any artifacts, the ability won't do anything.
